Postyield behavior of subchondral trabecular bone
Journal of Biomedical Materials Research, 1976AbstractCylindrical specimens of bovine subchondral trabecular bone were tested to uniaxial compressive strain levels of 75% to study energy absorption during pore collapse. Stress–strain curves were characterized by macroscopic yield at about 8% strain followed by a significant horizontal pore collapse regime.

Subchondral and Trabecular Bone Respond Differently to Exercise in Juvenile Sheep
The FASEB Journal, 2020Evaluating the responses of subchondral and underlying trabecular bone properties to exercise interventions have implications for understanding normal developmental processes as well as the etiology of diseases affecting these tissues.

Trabecular Bone Strain Changes Associated With Subchondral Bone Defects of the Tibial Plateau
Journal of Orthopaedic Trauma, 2002To measure trabecular bone strain changes resulting from three increasing subchondral bone defects in the medial tibial plateau.Cadaveric biomechanical model.Contact radiographs were made from coronal sections of human cadaveric proximal tibia under no load and loaded to 400 newtons (N).

Osteoporotic changes of subchondral trabecular bone in osteoarthritis of the knee: a 3-T MRI study
Osteoporosis International, 2011Subchondral trabecular bone structure was analyzed in knee osteoarthritis (OA) patients using 3-T MRI to investigate structural features of subchondral trabecular bone of knee OA. With OA progression, osteoporotic changes were observed in the lateral joint, showing a higher correlation than sclerotic changes in the medial joint.To investigate ...

Trabecular Bone Strain Changes Associated with Subchondral Comminution of the Distal Tibia
Journal of Orthopaedic Trauma, 2002To measure trabecular bone strain changes resulting from three increasing subchondral bone defects in the distal tibia.Cadaveric biomechanical model.Contact radiographs were made from sagittal sections of human cadaveric distal tibia under no load and loaded to 400 N. Digital images, made from contact radiographs of unloaded specimens, were compared to

In vivo structural analysis of subchondral trabecular bone in osteoarthritis of the hip using multi-detector row CT [PDF]
Osteoarthritis and Cartilage, 2011 With developments in clinical computed tomography (CT), in vivo analysis of patients' bone microstructure has become increasingly possible. We analyzed the subchondral trabecular bone of hip osteoarthritis (OA) patients using multi-detector row CT (MDCT) to closely examine the structural changes that occur as OA progresses.47 female hip joints were ...

Comparative Analysis of Bone Structural Parameters Reveals Subchondral Cortical Plate Resorption and Increased Trabecular Bone Remodeling in Human Facet Joint Osteoarthritis [PDF]
International Journal of Molecular Sciences, 2018 Facet joint osteoarthritis is a prominent feature of degenerative spine disorders, highly prevalent in ageing populations, and considered a major cause for chronic lower back pain.

Clinical Biomechanics, 2015
The subchondral trabecular bone is located deep inside the articular cartilage, with the subcapital region carrying up to 70% of the diurnal loads occurring in the hip joint. This leads to severe regional anatomical variations of subchondral trabecular bone in the femoral head and the purpose of this study was to examine whether osteoarthritis affects ...

Rheumatology International, 2009
The effects of bone turnover rate on subchondral trabecular changes and cartilage destruction were evaluated in an iodoacetate-induced osteoarthritis rat model. Thirty female rats were randomly divided into three groups as the ovariectomized group, the no-treatment group and the bisphosphonate medication group.
